Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed September 4, 1912. fierial No. 718,455.

To all whom it may concern:

Be it known that 1, ERNEST ARMSTRONG, a citizen of the United States, and a resident of Camden, in the county of Camden and State of New Jersey, have invented a certain new and useful Improvement in Lubricating Devices, of which the following is a specification.

My invention relates to lubricating devices, and more particularly to lubricating devices for car journals, and the invention is especially useful in connection with car journals which are inclosed in journal boxes s0 arranged and constructed that the lubricating devices cannot be inserted from the front end of the box.

One of the objects of the invention is to provide a lubricating device which is simple, durable and eiiicient and inexpensive to construct and maintain.

Another object of the invention is to provide a lubricating device, of the wick type, for car journals which may be readily slipped into place between the side of the journal and the adjacent side wall of the journal box from the top of the box by removing the bearing.

Another object of the invention is to provide a lubricating device of the above character which is especially adapted for journals having a small clearance between the journal and the sides of the journal box, and in carrying out my invention, I provide a thin upright wick-supporting frame having a yieldable part against the upright part of der that the lubricating device may be slipped into place between the journal and the side of the box, the compressible wicksupporting part being so arranged and constructed that when the lubricating device is fixed in position, the wick-supporting part will spring out into position to hold the lubricating portion of the wick in such position that it will rest by gravity lightly in contact with the journal without glazing.

The invention will be more readily under stood and the objects of the invention will more fully appear from the following description taken in connection with the accompanying drawings forming a part of this specification, and in which- Figure 1 is an end elevation of a lubricating device made in accordance with the pre the frame 1n orthat may be compressed in.

ferred form of my invention; Fig. 2 is a cross-sectional view of a journal box and ournal equipped with the preferred form of lubricating devices shown in Fig. 1, taken on line a-a of Fig. 3; and Fig. 3 is a side elevation of a journal showing the lubricating device in position.

Referring to the drawings, 1 is a car journal on which is mounted a bearing 2, the journal and bearing being inclosed in a journal box 3 having vertical side walls &4 and a bottom wall or floor 5 forming an oil well at the bottom of the box. lhe particular form of journal box for which this form of lubricating device is more especially adapted, is provided with inwardly projecting vertical ribs or upright pieces 6 extending inwardly from the front end of the side walls of the box into such close proximity to the journal 1 that it is impossible to insert the lubricating device from the front end of the box.

The form of lubricating device shown comprises a narrow upright wiclcsupporting frame 8 preferably made of sheet iron and provided with upper and lower flanges 9 9 for the purpose of strengthening the frame, the lower flange 9 being adapted to rest against a horizontal ledge 1.0 along the side of the journal box below the horizontal axial plane of the journal, from which the frame is supported, the frame extending along the side wall of the journal box and having a wiclcsupporting part 11 preferably formed ofsheet metal and extending downwardly and inwardly away from the adjacent side wall of the box. In the present form of my invention, this wick-supporting part consists of two sheet metal pieces E 12 riveted to the upright frame 8 at their upper ends, their lower ends being connected by a sheet metal strip 13 to which the wick 14L is secured. This inwardly projecting part is so arranged and constructed with respect to the upright portion 8 of the frame that it may be compressed in toward the upright portion of the frame in inserting the lubricating device between the journal and the adjacent side wall of the box; and in the preferred form of my in vention, this inwardly projecting wiclr-supporting portion is slightly curved, as shown in Fig. 1, and, in its stable or normal position, projects inwardly just far enough to hold the immediately adjacent portion of the wick in light contact with the immediately adjacent portion of the journal.

The wick 14, in the preferred form of my invention, comprises a. thick napped lubricating portion 15 which extends from the bottom of the wick-supporting part of the frame upward between the ournal and the upright portion of the frame above the hori- Zontal axial line of the journal, and a downwardly projecting lubricant-feeding portion 16 extending into the oil well at the bottom of the box; so that when the wick becomes saturated with lubricant, the part of the lubricating portion of the wick extending above the horizontal axial plane of the journal will sag over and contact lightly with the journal so as to lubricate the same.

The wick preferably is composed of longitudinal lubricant-feeding fibers 18 extending throughout the length of the wick, with lubricating naps woven therein at that portion of the wick which contacts with the journal.

To fit the lubricating device into the journal box, the hearings or brasses are removed and the lubricating device is taken in the operators hand and the compressiblewicksupporting part 11 is squeezed down against the upright part 8 of the frame so as to flatten the device a whole, and then the device is held in a vertical position and slipped in between the journal and the adjacent side wall of the box until the lower end or flange 9 of the lubricating frame rests upon the horizontal ledge 10. As soon as the compressible wick-supporting part 11 has passed below the horizontal axial plane of the journal, the hand may be released, and this compressible part will then spring out into its normal or stable position at which the lower end of the lubricating portion of the wick will be brought into slight contact with that portion of the jour nal at and below its horizontal axial plane. soon as the wick becomes thoroughly saturated with lubricant, as previously stated, the portion of the lubricating partf the wick extending above the horizontal axial plane of the journal will sag over and rest lightly against the journal.

While I have shown and described what I believe to be the preferred form of my invention, it will be obvious to those skilled in the art that various changes may be made in the arrangement and construction of the supporting frame and of the wick without departing from the spirit or scope of my invention, and I do not wish to be understood as limiting myself other than as indicated in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The combination of a journal box having an oil well in the bottom thereof, a journal in the box, a bearing on the journal, a wick-supporting frame in the box at one side of the journal having a wick-supporting part yieldable toward and away from the side wall of the box, and a wick secured to said part and having an upwardly pro jecting lubricating portion extending from said part above the horizontal axial plane of the journal and having alubricant-feeding portion extending downward into the oil well, whereby the frame may be slipped in place from above and when in place a portion of the wick will be held in engagement with the journal and when the wick is saturated with lubricant, the portion of the wick above the horizontal axial plane of the journal will sag over by gravity upon the journal.

2. The combination of a journal box having an oil well in the bottom thereof and a horizontal ledge on the side wall thereof, a journal in the box, a bearing on the journal, an upright wick-supporting frame in the box supported on said ledge and having a wick-supporting part secured thereto and extending downwardly a d inwardly away from the side wall of the box and compressible toward the side wall of the box, and a wick secured to said part and having an upwardly projecting napped lubricating portion extending from said part above the horizontal axial plane of the journal and having a lubricant-feeding portion extending downward into the oil well, whereby the frame and wick may be slipped in place from above and when the wick is saturated with lubricant, the portion of the wick above the horizontal axial plane of the journal will sag over by gravity upon the journal.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
